Title: Cabin pressure rate controller
IPC: B64D13/04
Filed: 1969-01-06
Abstract: 1,247,624. Pressurizing aircraft. UNITED AIRCRAFT CORP. 6 Jan., 1969 [17 Jan., 1968], No. 763/69. Heading F4V. [Also in Division G1] The air pressure inside an aircraft cabin is automatically regulated by an electric control system fed with signals representing the measured pressures inside and outside the cabin, and the predetermined values of the pressures corresponding to cruising and landing altitudes of a particular flight plan. The predetermined values of ambient pressure at the cruising altitude P A SET and at the landing altitude P L SET are set up initially on networks 2, 4, e.g. potentiometers with barometric correction. A further signal P iso  representing the scheduled cabin pressure at cruising altitude is also provided. During ascent, the signal representing the measured cabin pressure P c  and the signal P iso  are fed to a difference circuit 12 giving an output indicative of the remaining cabin pressure difference #P c . The signal representing the measured external pressure PA and the signal P A SET are fed to a difference circuit 30 giving an output indicative of the remaining external pressure difference #P A . The #P A  signal is fed to a function generator giving an output proportional to the ratio of the desired rate of change of cabin pressure to #P c  which is combined with the #P c  signal in a multiplier 37 giving an output proportional to the desired rate of change of cabin pressure P CD . This signal is integrated in a circuit 42, the resultant signal P CD , representing the desired cabin pressure, being compared with the measured cabin pressure signal P c  producing an error signal E which is fed to a valve and actuator to reduce the error signal to zero. A portion of the error signal is fed-back and if this portion exceeds preset limits, as determined by a tracking circuit 46, a feedback signal is fed to a summation circuit 40 to prevent large error signals. As an alternative, Fig. 2 (not shown), the desired rate of change of cabin pressure signal P CD  is compared with the actual rate of change of cabin pressure signal P c  to produce the error signal. The above-described device may be used in conjunction with features described in Specification 1,128,936 which is referred to, and the tracking circuit 46 may be that described in Specification 1,128,937 which is also referred to.
Patent GB-900955-A (GB)
Title: Devices for regulating the delivery of reciprocating fuel injection pumps
IPC: F02M59/36
Filed: 1959-01-09
Abstract: 900,955. Fuel-injection pumps. BESSIERE, P. E. Jan. 9, 1959 [Jan. 13, 1958], No. 848/59. Class 102(1). [Also in Group XXIX]. The injection period of a reciprocating fuel pump 41, 42, Fig. 1, is controlled by the engine water or lubricating pump 1 or a separate gear pump, the delivery from which acts to lift an adjustably spring-loaded plunger 4 away from an adjustable abutment 7, which delivery is also connected to both a discharge conduit 10, via a passage 9, the area of which is regulated by a slide valve 11, and to the operating surface of the latter; the valve 11 is loaded by an adjustable spring 12 and its movement is defined by abutments 14, 31, the former of which is adjustable. A second slide valve formed on part 4 controls the area of another passage 16 in a conduit 17 that joints a discharge port 19 with a cylinder 18 in which slides a spring-loaded valve 20 in a discharge conduit 38, 39 leading from the injection pump cylinder 42; valve 20 carries an abutment 21. An engine-driven cam 46 causes reciprocation of the injection-pump piston 41 whilst a second cam 54 operates an auxialiary reciprocating- pump 48, 49 the delivery of which is directed to the cylinder 18 via a conduit 50, the cylinder 42 via a conduit 43, and to a further spring- loaded valve 56 in the conduit 17. A passage 40 is provided across the valve 20 for balancing purposes. As the piston 41 moves downwards the piston 48 travels upwards and the fuel delivered by the latter acts on valves 56 and 20 to close conduits 17 and 38, 39 respectively; when piston 41 uncovers conduit 43 then the piston 48 forces fuel into the cylinder 42. Upon the piston 48 commencing its downward stroke the valve 56 opens and piston 41 begins to slide upwardly whereupon conduit 43 is closed. The fuel delivered by piston 41 passes to the fuel injectors through a pipe 44 until the spring of valve 20 has moved the latter to open conduits 38, 39 whereupon injection ceases; this point is determined by the rate at which fuel from cylinder can flow through passage 16, the degree of restriction of which depends upon the delivery pressure of pump 1, and hence engine speed. As the latter increases the throttling effect of passage 9 is increased and that of passage 16 is reduced. In a modification, either one or both valves 4, 11 is or are provided with a through passage 25, Fig. 2, one end c of which is widened and the other end, together with the associated part of the inlet passage 27, is made of circular rectangular, triangular or oval shape for throttling purposes. The valve is prevented from rotating by rib 32 engaging a flange 33 that has a dash-pot action in a cylinder 34. The valve is formed with a groove 37, recess 35 and a slot 36 opening into the passage 27 for balancing purposes.

Abstract: 982,163. Automatic exchange systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 8, 1963 [Jan. 11, 1962], No. 869/63. Heading H4K. In an arrangement for preventing possible reseizure of a called line which remains looped after the calling party hangs up, relay S energizes in the test circuit when the line is seized by a final selector and inserts its second winding and relay L so that the latter also energizes. Thus, when the test circuit is opened in the final selector owing to the release by the calling party, relay L falls back and makes a holding circuit over the loop for a third winding of S. The impedance connected to the test wire is now such that a final selector test relay cannot energize. A warning tone is given to the called party over the holding circuit. The arrangement may be applied in a PABX in which several incoming calls are liable to be connected in succession to the same extension.

Title: Improvements in mechanical remotely-actuated manipulators
IPC: B25J19/00
Filed: 1962-01-10
Abstract: 963,930. Manipulators. SAINT-GOBAIN NUCLEAIRE. Jan. 10, 1962 [Jan. 10, 1961], No. 999/62. Heading B4Q. A manipulator having a master end including a control gripper PC operating a gripper PP on the slave end is mounted on a block 9 removably mounted by a sliding action in an aperture in the wall 50 of a hot cell. The block makes a seal with the wall by a joint 117 and shafts, e.g. shaft 24, transmitting motion from the master to the slave end through the block are sealed to the block by joints 122, 123, 126, 127. The manipulator permits of three degrees of movement defining the position in space of the gripper PP and four specific movements of the gripper itself including opening and closing the jaws, these seven movements being produced by imparting similar movements to the master end, the transmission mechanism shown on the master side of the wall 50 being substantially duplicated on the slave side. The manipulator comprises a tubular arm 2 mounted on a fixed horizontal axis A provided on a frame 53 secured to the block 9, a part 10 rotatable on bearings 10a, 10b in the arm 2 having a fork 16 providing an axis B on which is pivoted a guide arm 1. A tube 3 rotatable on bearings 3a, 3b in the arm 1 has a fork 60, Fig. 5, pivotally carrying about an axis G a tube 61 in which a tube 62 is rotatable. The tube 62 carries a handgrip 63 and a lever 64 for controlling the gripper jaws (Fig. 6, not shown). An extension 30 of the arm 1 carries a Cardan joint 20 connected to a tie 4, the other end of the tie being connected to a Cardan joint 21 on an arm 5 pivoted on the axis A, the members 2, 10, 30, 4 and 5 forming a parallelogram. This parallelogram is deformable in the vertical plane of Fig. 1 or 2 and may also be twisted so that the extension 30 and tie 4 depart from that plane, the combination of these two kinds of movements permitting the three movements in space of the gripper PP. The rotation of the arm 2 about the axis A in the plane of Fig. 1 is transmitted to a shaft 11 connected by a flange 11a to the arm, this motion being connected through bevel pinions 12a, 12b to a shaft 12 coupled to a shaft 23 extending through the block 9. Rotation of the arm 5 about the axis A in the plane of Fig. 1 is similarly transmitted through a shaft 14, pinions 15a, 15b, shaft 15 to a shaft 25. The rotation of the tube 10 within the arm 2 due to twisting of the parallelogram is imparted to an element 17 rigid with the tube 10 and connected to a shaft 18 through a Cardan joint 19 centred on the axis A, the shaft 18 being coupled to the shaft 24. The four specific movements of the gripper itself are obtained by moving lever 64, rotating handgrip 63 about two axes x-y and G relatively to the tube 3 and rotating tube 3 in the arm 1, these motions being transmitted to three further shafts (Fig. 3, not shown) traversing the block 9 by systems of cables and pulleys (Figs. 7-9, not shown). The manipulator may be removed from the wall by bringing the slave end into alignment with the arm 2 and withdrawing the block 9.
